我已经能够获得事件在我的木偶控制器火，像这样：Backbone.js的木偶ItemView控件单击事件不工作
...snip...
var Controller = {};
_.extend(Controller, Backbone.Events);
// private
var Layout = Marionette.Layout.extend({
template: _.template(layout),
regions: {
inspectorStart: "#inspector_start",
loginStart: "#login_start",
playerStart: "#player_start"
}
});
// private
var _initializeLayout = function() {
console.log('initialize Start Layout...');
Controller.layout = new Layout();
Controller.layout.on('show', function() { **// This works**
Controller.trigger('startLayout:rendered'); **// This works**
});
vent.trigger('app:show', Controller.layout); **// This works**
};
// Listen for events ///////////////////////////////////////////
// controller attach a sub view
Controller.on("startLayout:rendered", function() { **// This works**
console.log('startLayout:rendered =>StartController'); **// This works**
// render views for the existing HTML in the template,...
var inspectorStartView = new InspectorStartView();
// and attach it to the layout (i.e. don't double render)
Controller.layout.inspectorStart.attachView(inspectorStartView);
Controller.trigger('inspectorStart:show', inspectorStartView); **// This works**
...snip...
然而，当我尝试使用扩展木偶ItemView控件我可以不会让事件或触发器起作用。
// views/InspectorStartView.js
// -------
define(["jquery", "marionette", "text!templates/InspectorStart.html"],
function($, marionette, template){
var InspectorStartView = marionette.ItemView.extend({
template: template,
events: {
'click .starting_thumbnail' : 'start'
//'click #inspectorStart' : 'start' **// didn't work either**
},
//I had also tried triggers
triggers: {
//'click .starting_thumbnail' : 'inspectorStart:start'
'click #inspectorStart' : 'inspectorStart:start' **// didn't work either**
},
start:function(){ **// Doesn't get called**
console("Caught InspectorStartView click")
this.trigger("inspectorStart:start")
}
});
// Returns the View class
return InspectorStartView;
});
这里是模板：
<!-- InspectorStart.html -->
<div id="inspectorStart" class="thumbnail starting_thumbnail">
<img src="/img/detective-97715888.jpg" alt="Inspector" width="200px" height="300px">
<div class="caption">
<h3>Inspectors Enter Here</h3>
<p>Den Masters, Teachers, Parents, House Mothers, this is where you start.</p>
</div>
</div>
我也必须创建starting_thumbnail类，这样我会得到一个指针：
.starting_thumbnail{
cursor: pointer;
}
我需要做别的事情让div可点击？
在我第一次尝试我App.vent通过，并试图用它来无济于事我现在扩展控制器{}与_.extend（控制器，Backbone.Events）;
在从@Ingro一些调试建议我登录的ItemView控件这是什么。$埃尔ID。这个： console.log（[“InspectorStartView initalise”，this。$ el]）
这里是输出。有nodeName：“DIV”和localName是div。

当然上面是在初始化方法里面。我想看看创造一个“新”一前一后的区别：
/ controller show inspector in the layout/subview
Controller.on('inspectorStart:show', function(inspectorStartView) {
console.log('show inspector start view');
console.log(**'InspectorVartView instance this.$el : ', inspectorStartView.el**);
Controller.layout.inspectorStart.show(inspectorStartView);
});
输出小得多：
InspectorVartView instance this.$el :
<div>
<!-- InspectorStart.html -->
<div id="inspectorStart" class="thumbnail starting_thumbnail">…</div>
</div>
@Ingro被包裹在一个div为什么会是怎么回事？
有没有人看到我在做什么不正确？
感谢，
安德鲁jsFiddle（见下文评论）
div #inspectorstart是您视图的父元素，您的$ el？在这种情况下，你应该在你的活动中试试这个：''click'：'start'' – Ingro 2013-02-18 00:19:09
@Ingro谢谢你的建议。我尝试'点击'：'开始'它不起作用。我把名字从'start'改为'fire'，看看名字是否有所不同。它没有什么区别。它似乎应该是直截了当的，但由于某种原因，它不是， – KingAndrew 2013-02-18 08:24:42
这是一个jsFiddle（http://jsfiddle.net/KingAndrew/SeDeL/）的开头。我不确定如何添加骨干和牵线木偶，但这是一个开始。 – KingAndrew 2013-02-18 08:51:26
